I'm trying to fetch e-mails into Redmine via IMAP.

The e-mails I'm generating look like this:

FooBar Ltd 
123456
http://example.com/Foobar-Ltd-123456.html

Project: backend
Tracker: Dataerror

Beschreibung:
This is the description

===========================
CLIENT_IP: 192.168.1.215
HTTP_USER_AGENT: mozilla/asdfjköl

I try to fetch them into Redmine via this command:

rake -f /var/www/projects/redmine/Rakefile redmine:email:receive_imap \
RAILS_ENV="production" host=example.com port=993 ssl=true username=redmine \
password=1234 project=myproject tracker=other \
allow_override=project,tracker,category,priority \
move_on_success=read move_on_failure=failed

But the e-mails get moved into the failed folder.

I had this setup running some time ago with a different e-mail generator but pretty much the same template, and I can't figure out why it's not working. The permissions seem to be OK too.

In order to further debug this issue, I need some logfiles. Are there any logfiles written by this command? Or are there any other suggestions to solve this issue?

My environment:
